To all whom #may concern:

' Be it known that I, 'EMIL BOMMER, a citizen ofthe United States of America, and a resident of'the borough of Brooklyn, county ofKings, lcity and State'of New .Yorin have invented certain new andluseful which is effected by'withdrawing'saidfy eX- traneous means.

The invention isy .shown invarious embodilments in the drawingsand will be more fully described' hereinafter and iinally .pointed out inthe claims.l y

In the accompanying drawings :Y Figure 1 is aside-view of a `verticaltype invention,

Fig. 2 isan endview thereof looked into inoperative position, so as toenable thedoor to be used without the operation of the spring-action ofthe hinge.

Similar characters of reference'indicate corresponding parts throughouti the-various figures. j I

Referring to the drawings, and more particularly to Figa 1, one form ofthe vertii lcal type of floor-surface spring-hinge' is shown therein, the essential 'parts' of? which Specification of Letters Patent.

'l one beveled face and-one verticalface. lte'rmediate the springeholders 15 and 16, and connecting therewith, a coil-spring 19 'isarranged At the side off-the framelO, a

Application iled. May 2, 1914. Serial No. 835,888.'`

are described and claimedin my copending application filedl April 15,' 1913, under Serial No. 761,140, to which reference is hereby made. The parts thereof consisty of a hinge-frame 10`in which a spindle 11l is 'journaled,l the'spindle 11 having va squared lower end 12 non-rotatably seated in a'fioor plate 13, which issecured to the floor by screws 14e.A The spindle 11 is provided with Va-lowerspring-holder 15 and an upper adjustable spring-holdery 16', said adjustable j spriiigfholder 16 has a tension collar-16a'in, conjunction therewith; thespring-holder `yl'andtension-collar 16a haveinterior and exterior projections or lugs, the exterior projections or lugs 1-7 and 18 each having locliingmechanism is arranged which is provided with projections-21. and 22, which.

engage the vertical-facesQS'and 2t of the bev-eled'lugs 17 and 18, butV whichk projections 22 and 21 maybe moved out of the path ofthe verticallfaces,.so as to be released therefrom, so as to pass over the beveled-faces ofthe projections or lugs.-17 and 18. lVhen so ymovedfout ofcontact with the vertical faces of these projections 17 and "18, the spring-action is disengaged from the hinge-frame andthe door may be opened and-willremain open without any spring- `v yaction'until lthe door is `again closed, which act of closing the door automatically restores the spring-'action to the door;

In order to lock this mechanism into a Vposition so astoretain the spring-action of the spring-hingein disengaged or inoperative position, so `thatvthe door can be freely operated ini either 'direction beyond the closed! position without any spring-action, the frame 10 and side-plates 4:0 yare provided with an openingy 25, through which a rod a-for nail,` etc., `is-passed'orinserted under the-'lockingmechanism 26 when said lockingmechanism is in raised position and the lugs 21 and 22 areout of engagement with the vertical faces .23 and 24. This nail or lrod 25a holds these parts in inactive position,l and thereby the door may beopened or'closed orj moved into any position without anyv action ofthe spring, until the :said nailor rod 25a'is withdrawn.

ln= Fig.' 3'l another' embodiment is shown, which shows the horizontal type of floor In-v surface spring-hinge, and which consists of a hinge-frame 39 having guide-plates 39a, said hinge-frame 39 being fastened to a door 49 and being journaled on a stationary-member 43 of the hinge, said stationary member 43 having spaced vertical rollers k35and 36, the member 43 being socketed, as shown at 43a to a. Hoor-plate 46 which is fastened tothe floor 48 by screws 47 or other means, a bearing-member 33 havinga face 37 to engage the vertical rollers 35`and 36,.a lug 37?'preferably on its lower side and disk rollers 39? at its upper and lower` sides, an

extension-rod 30 on the bearing-member 33,

- member 33- and its rod 30 being. respectively iguided ,to forward and backward movement a lcoiledspring 3l onsaid rod, the bearingwithin,the .hinge-frame by rollers 39.".vbetweenthe guide-plates 39LL of the hingeframe and in a. perforation 30a of the hingef frame 39.` The door casing 44 is .shown in @cross section. v The side-,plates are shown 'When it is' desired to disengage the `springaction from the-door,;the door is opened to eitherside lor directionlshown in,Fig.3

openedin one direction), whereby the spring 31 is compressedA until the bearing member 37- is pushed :beyond the ends ofthe vguideplates, 39L suiiiciently to permit the insertion. ofv a nail, or-piece of wire 38 between and non-rotatably socketed in Ithezsquared v or non-circular *socket of a vfloor-plate by `the lug 37a and the ends 39c of theguideplate 39, or the nail or piece of wire may be inserted in perforations 39eof the guidevplates 39,-` thereby locking the vcoil-spring 31 into inoperative position ask shown in Fig. 3; by this means the face 37 of the bearingmemb'er 33 is maintained o ut of ,contact with the rollers 35v and 36, and thereby thejdoor may. be .moved independently of the.- action `rof the spring. f Thespring actionv may, at

any time be restored toy the door by again "opening the door ateither side. as shown in Fig. 3, and withdrawing the nail or wire 38.

In Figs. 4, 5. 6,7and 8 stillanother Vembodiment of the vertical-type ofV floorsurface spring-hinge is shown.^ yThis type fofwhingc differs essentially fromftheembodifment lheretofore -described and ishownvin Figs. land 2, which hasfthesplindle rigidly means of the correspondingly square-shaped Vor noncircular end ofthe spindle, whereas, in the type shown in Figs.l 4, 5,' 6, 7 and v 8, the spindle may be disconnected lfromthe y-'floor-plate'so as to rotate inthe floor-plate Kwithout spring-action when-thefdoor isvto be held open.; In Fig, 4, .80,representsthe door, 81 represents the'fioor.; the spindle 60 M has adownwardprojection 61, whichis j ournaled in the1floor-,plate 62.1": The. springholder. 63 with its spring 64 is arranged in the usual well-f. known manner, and the spindle 60 is provided with an enlarged flange 65, rwhich has a cut-out portion 66 therein.

is arranged a vertically-movable springvactuated pawl or detent 68, which projects out of the frame with its nose-piece 69 and operates upon and contacts with avertlcallyto `the hoor-'plate' `62. ,andv the spring-action is. in engagementjto 'close'` they 'door when ysameisoperatedf.'4 If, however, it is desired .tohold vthe door open without theaction v of the spring,fthe detent 69 ,is pushed downward. and forces the Ivertically-niovable cylindrical-memberor plug 7 O ldownwardfb'elowthe enlarged-liange 65 -of the spindle 60,' and permits thereby the spindle60, together with the hinge-frame 67 to rotate inthe `Hoor-plate 62, and the flange 65 to pass over [In the frame'67 of this type of 'spring-hinge the verticallyfmovable cylindrical-memberv or plug 70 without4 engaging vvtherelwith.. while the door is open; when, Ihvvever," the door lis again lbrought'to closed position, the `ver- Y tically movable cylindrical-member orplug 70 under the action of the spring 7l ,is again,

brought into connection withthe fiange 65 of'spindlef60, and the spring-action is thereby automaticallyrestored tothe. door. This is clearly shown in Fig. 6.

In order to lock the sprlng-action-in disengaged position when itjisdes'ired to freely i operate the. door in either direction without the spring-action of the spring, the frame 67 and 'side-plate 40 are provided with an opening 73,',through which a ynail 74 `or, piecelof wire orwsimilar obstruction is inserted, which also passes through acorresponding lopening 75 in the detent 68. By this-passing through of these parts, the detent is lockedin its downward position, thereby preventingthe vertically movable,

lcylindrical plug 7 O from againv connecting withthe'flange 6 5"- ofl the spindle GOuntil said nail v74 or other similar obstructionV is withdrawn from the opening?? 3 of theframe 67 for the purpzosegofl againrestoringthe spring-action of 'the springto-V thef'. hinge.

This is clearlyshown in Figs. y 5 andff.Y

A modiied form of this device` is shown -vi'n'Fig 7, in y which the frame is provided' with anjopening 7 6,; and with a detent with a cut-out portion 77, which portion islocked by .the nail` or rod described.

i Another embodiment -of my 4invention is shown in Fig. 8, in which the yerticallymovable cylindrical-member 'or plug 70 is provided with a groove 78, which groove,

when it is in registration with an opening 79 of the door-plate 62 permits a nail or piece of wire as that described to be passed therethrough and to lock the cylindrical member 70 in its downward position. By this locking action, the member 70 is held in its downward position and out of connection with the cut-out portion 66 of the enlarged flange 65 of the spindle 60 while the door is desired to be operated without any spring-action of the spring, and the spring action may be restored to the ldoor at any time by withdrawing said nail or piece of wire or rod.

In the embodiments described, where necessary or desirable, a suitable hole corresponding to the location of the hole in the hinge-frame can be made in the side-plates '-10 so that the extraneous means as a wire, nail, or rod, etc., may be inserted without unscrewing the side-plates.

I have described several embodiments of my invention, but it is clear that changes may be made therein without departing from the spirit of the invention as defined in the appended claims.

I claim:

l. In a spring hinge, the combination of a hinge frame, a spring control element comprising a spindle and a spring actuated member carried thereby, and rotatable with' respect thereto during spring action of the door, means adapted to be moved with respect to the said spring control element to make the spring action thereof inactive with respect to the door, a casing inclosing said hinge, said casing and said first named means being provided with registering passages in the inactive position of said spring control element forming an uninterrupted passage through the hinge, and independent means separate and detached from said hinge adapted to be engaged with said registering passages from either side of the door to retain said first named means in said moved position until said independent means is removed, said casing forming an immovable support at each side of the hinge for said independent means.

2. In a spring hinge, the combination of a hinge frame, a spring control element comprising a spindle and a spring actuated member carried thereby and rotatable with respect thereto during spring action of the door, means adapted to be moved with respect to said spring control element to make the spring action thereof inactive with respect to the door, said means normally adapted to return to its original position upon the closing of the door, a casing inclosing said hinge, said casing and said iirst named means being provided with registering passages in the inactive position of said spring control element forming an uninterrupted passage through the hinge, and independent means separate and detached from said hinge adapted to be engaged with said registering passages to retain said first named means in the said moved position until said independent means is removed, said casing forming an immovable support at each side of the hinge for said independent means.

3. In a spring hinge, the combination of a hinge frame, a spring control element comprising a spindle and a spring actuated member carried thereby and rotatable with respect thereto during spring action of the door, means adapted to engage the spring control element to establish connection between the same and the door, means adapted to be operated to disenga'ge said first named means from said spring control element, a casing for said hinge, said casing and said disengaging means being provided with registering means in the inactive position of said spring control element, and independent means separate and detached from said hinge, adapted to engage said registering means to retain said disengaging means in disengaging position until said independent means is removed.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
